Wiegand : Notes on Saxifraga and Primula 389 



4 Saxifraga austromontana sp. nov. 



Densely caespitose, glabrous, the rootstocks densely scaly- 

 bracted : stems divaricately ascending (7-18 cm. high, .75 mm. 

 thick), slender, usually purplish : leaves thick and firm, crowded 

 on the caudex (7-10 mm. x 1.5 mm.), linear oblong, slightly 

 narrowed below, gradually acute or almost acuminate at the apex, 

 terminated by a stout white bristle, shining y spinulose-ciliate from 

 the base to within 1.5 mm. of the tip : cauline leaves much smaller, 

 4-6 mm. long, linear-subulate : flowers numerous, 4—1^2 or even 

 more, on slender slightly glandular peduncles (.4-10 mm. long), 

 in a convex or often oblong open cyme, the ^yer sometimes quite 

 distant : calyx-lobes 2 mm. long, ovate, obfrcfse, rarely apiculate, 

 sparingly glandular : petals white, spotted with orange dots below 

 the middle, and with deep-purple dots above, elliptic-oblong (5.5 

 mm. x 2 mm.), broadest just below the middle, obtuse at the 

 apex, rounded and somewhat truncate at the base, not at all 

 unguiculate : stamens i-| shorter than the petals : ovary deltoid : 

 styles very short, not over | the length of the ovary. 



Cascade Mountains of Washington to Alberta, and southward 

 along the Rocky Mountains to New Mexico. 



Specimens examined : Cascade Mts. (Lyall) ; Tunnel Mt., 

 Alberta (W. C. McCalla, no. 2287 (1899)); Colorado (Parry, no. 

 168 ; Hall and Harbour, no. 197 ; Wolf, no. 802); New Mexico 

 (Heller, no. 3775). 



This species differs from 5. broncliialis in its more subulate, 

 darker green leaves, with fewer ciliae near the apex ; more slender, 

 often purple stems ; many-flowered convex or oblong cymes, more 

 slender pedicels ; smaller, white petals with purple dots above, 

 and not unguiculate at the base ; stamens shorter than the corolla ; 

 and smaller capsules with much shorter styles. It probably in- 

 eludes all of the so-called 5. broncliialis from the Rocky Moun- 

 tains south of Alaska. 



v Primula Maccalliana sp. nov. 



Mistassinica 



Not of Michx. 



Low but not very slender (4-1 2 dm. high) : leaves from broadly 

 spatulate to obovate-cuneate, mostly quite broad, the larger usu- 

 ally sessile by a wedge-shaped base, the smaller rarely contracted 

 into a short margined petiole, thick and rather fleshy, mostly 

 glabrous and pale green above, more or less mealy beneath, obtuse
